FIELD OF THE INVENTION

The present invention relates to a method for promoting eye health in acompanion animal comprising: administering to a companion animal acomposition comprising at least one polyphenol selected from the groupconsisting of rosemary, rosemary extract, coffeic acid, coffee extract,turmeric extract, cucurmin, blueberry extract, grapeseed extract,rosemarinic acid, tea extract, and mixtures thereof.

BACKGROUND OF THE INVENTION

Vision loss in companion animals is often related to free radical damageto the companion animal lens and corneal epithelial cells, environmentalstress such as sunlight, and the normal stress associated with aging ofthe companion animal. A free radical is a highly reactive molecule thatbinds to and destroys body components. As a result of the companionanimal's eye reliance on light to function properly, the eyes areparticularly vulnerable to free radical attacks. While light aids acompanion animal on its ability to see, light also creates additionalfree radicals that enhance vision loss by promoting cell and membranedamage of the companion animal eyes.

Blue light (400-500 nm) of the visible spectrum has a relatively highenergy, can penetrate tissue(s) and has been shown to have a majorimpact on photoreceptor and retinal epithelial cell function, inducingphotochemical damage and apoptotic cell death. The blue light comes fromthe glaring snow or water reflex and can be a hazard to sporting,hunting, working, rescuing and fishing dogs. Exposure to visible bluelight causes an increase in both mitochondrial and nuclear DNA lesionsand an increase in free radical production in retinal epithelial cells.Blue light induced free radical damage to the mitochondria can beblocked either by inhibiting the mitochondrial electron transport chainor by mitochondria-specific antioxidants.

Additionally, as the companion animal ages, free radicals participate inthe aging in the companion animal eye. Cataract formation which isthought to be triggered by the free radical stress on the companion eyeis primarily associated with advancing age of the companion animal.

There still exists a need for a composition that treats and aids inpromoting eye health of a companion animal.

It is therefore an object of the present invention to provide method ofimproving eye health in a companion animal comprising administering acomposition that prevents or treats environmental stress, prevents ortreats age associated stress, slows down cataract progression, improvesvision, and maintains younger eyes in the companion animal.

Carotenoids

The composition of the present invention can comprise a carotenoid. A“carotenoid” is a class of pigments occurring in the tissues of higherplants, algae, bacteria and fungi. They are usually yellow to deep red,crystalline solids, soluble in fats and oils, insoluble in water,highmelting, stable to alkali, unstable to acids and oxidizing agents,their color is easily destroyed by hydrogenation or by oxidation, andsome are optically active. Carotenoids are natural pigments synthesizedby plants and microorganisms that are thought to function as lightabsorbing pigments during photosynthesis and to protect cells fromphotosensitization. Structurally, carotenoids consist of eightisoprenoid units joined so that their arrangement is reversed at thecenter of the molecule. Carotenoids have demonstrated biologicalactivities in addition to maintaining oxidative balance. Carotenoidstructure strongly affects the physical properties. chemical reactivityand biologic functions of these compounds. It has been suggested thatthe size, shape, hydrophobicity and polarity of individual carotenoidsmay dramatically affect the bioavailability, absorption, circulation,tissue and subcellular distribution and excretion in mammals.

When a carotenoid is present, the carotenoid is selected from the groupconsisting of lutein, astaxanthin, zeaxanthin, bixin, lycopene, andmixtures thereof.

Lutein is an antioxidant, belonging to a class of lipid-solubleyellow-to-red pigments known as carotenoids. Lutein and zeaxanthin arestructural isomers of one another. Lutein can be extracted incrystalline form from marigolds. Dietary sources of lutein includemustard greens, spinach, kale, broccoli, leaf lettuce, green peas,brussel sprouts, corn, some squash and green beans. Lutein is powerfulantioxidant believed to protect the body and eyes from damaging freeradicals. It is the main carotenoid found in the retina of the eye, andmay be effective in the treatment of cataracts.

Amino Acids

The composition of the present invention can comprise an amino acid.Amino acids are the “building Blocks” of the body. Besides buildingcells and repairing tissue, they form antibodies to combat invadingbacteria & viruses; they are part of the enzyme & hormonal system; theybuild nucleoproteins (RNA & DNA); they carry oxygen throughout the bodyand participate in muscle activity. When protein is broken down bydigestion the result is 22 known amino acids. Eight are essential(cannot be manufactured by the body) the rest are non-essential (can bemanufactured by the body with proper nutrition).

When an amino acid is present, the amino acid is selected from the groupconsisting of Lysine, Taurine, Histidine, Carnosine, Alanine, Cysteine,and mixtures thereof.

L-lysine is an essential amino-acid that has been shown to significantlyreduce virus shedding in affected cats and decrease the duration offeline herpes virus-1 (FHV-1) infection, which is a very commoninfection in cats. FHV-1 is associated with many ocular diseases in catsincluding conjunctivitis, keratitis, corneal ulceration, symblepharonformation, L-lysine suppresses FHV-1 replication by competing witharginine for incorporation into the viral genome. The composition of thepresent invention may comprise at least about 0.05% of Lysine, by weightof the composition, from about 0.05% to about 10% of Lysine, by weightof the composition, from about 1.5% to about 5% of Lysine, by weigh ofthe composition.

Taurine is an amino acid used as a building block of all the other aminoacids; it is found in the eye, heart muscle, white blood cells, skeletalmuscle, and central nervous system. Taurine and sulfur are considered tobe factors necessary for the control of many biochemical changes thattake place in the aging process; aids in the clearing of free radicalwastes. Taurine is a sulfur-containing amino acid that is essential tothe cat because a cat has a limited ability to synthesize it fromcysteine, which is a precursor amino acid in most animal species.Therefore cats have a nutritional requirement for taurine. Nutritionalretinal degeneration and feline central retinal degeneration areidentical and associated with taurine deficiency in cats. Taurinedeficiency affects the cones in the retina, which are most prominent inthe area centralis which is located dorsetemporal to the optic disc. Thecomposition of the present invention may comprise at least about 0.05%of Taurine, by weight of the composition, from about 0.05% to about 10%of Taurine, by weight of the composition, from about 0.1% to about 5% ofTaurine, by weight of the composition.

Histidine is found abundantly in hemoglobin. Histidine is a precursor ofhistamine, a compound released by immune system cells during an allergicreaction. Histidine is needed for growth and for the repair of tissue,as well as the maintenance of the myelin sheaths that act as protectorfor nerve cells. Histidine is further required for the manufacture ofboth red and white blood cells, and helps to protect the body fromdamage caused by radiation and in removing heavy metals from the body.The composition of the present invention may comprise at least about0.05% of Histidine, by weight of the composition, from about 0.05% toabout 10% of Histidine, by weight of the composition, from about 0.1% toabout 5% of Histidine, by weight of the composition.

Carnosine has excellent potential to act as a natural antioxidant withhydroxyl radical, singlet oxygen scavenging and lipid peroxidaseactivities. A striking effect of carnosine is its demonstrated abilityto prevent, or partially reverse, lens cataract. Carnosine protects thecrystalline lens from oxidative stress-induced damage. Used togetherwith vitamin E and other antioxidants, it has an optimum effect, it isbelieved that Carnosine may reduce the destruction of valuable proteinsand DNA by sugar molecules, a process known as glycosylation. Carnosinemay help prevent damage from glycosylation, ridding the system of anyabnormal substances and leaving it free to function optimally. Thecomposition of the present invention may comprise at least about 0.05%of Carnosine, by weight of the composition, from about 0.05% to about10% of Carnosine, by weight of the composition, from about 0.1% to about5% of Carnosine, by weight of the composition.

Alanine is a nonessential amino acid that can be manufactured by thecompanion animal from other sources as needed. Alanine is one of thesimplest of the amino acids and is involved in the energy-producingbreakdown of glucose. In conditions of sudden anaerobic energy need,when muscle proteins are broken down for energy, Alanine acts as acarrier molecule to take the nitrogen-containing amino group to theliver to be changed to the less toxic urea, thus preventing buildup oftoxic products in the muscle cells when extra energy is needed. Alanineis found in a wide variety of foods, but is particularly concentrated inmeats. The composition of the present invention may comprise at leastabout 0.05% of Alanine, by weight of the composition, from about 0.05%to about 10% of Alanine, by weight of the composition, from about 1% toabout 5% of Alanine, by weight of the composition.

Cysteine functions as an antioxidant and is a powerful aid to the bodyin protecting against radiation and pollution. It can help slow down theaging process, deactivate free radicals, neutralize toxins; aids inprotein synthesis and presents cellular change. The composition of thepresent invention may comprise at least about 0.05% of Cysteine, byweight of the composition, from about 0.05% to about 10% of Cysteine, byweight of the composition, from about 0.2% to about 5% of Cysteine, byweight of the composition.

Antioxidant

The composition of the present invention can comprise an antioxidant. Anantioxidant is an enzyme or other organic molecule that can counteractthe damaging effects of oxygen in tissues. Although the term technicallyapplies to molecules reacting with oxygen, it is often applied tomolecules that protect from any free radical. When an antioxidant ispresent, the antioxidant is selected from the group consisting ofVitamin E, Vitamin C, Vitamin A, CoQ10, and mixtures thereof.

Vitamin E is a lipid soluble compound and the most significantantioxidant activity of vitamin E is localized to cellular membranes.Vitamin E maintains oxidative balance by protecting cellular membranesfrom lipid peroxidation. Vitamin E is a lipid soluble antioxidant andprovides defenses against cellular oxidative damage. All vitamin E inthe companion animal is derived from the diet and includes multiplechemical forms. Major dietary sources of vitamin E are vegetable oils,margarine and shortening, with nuts, seeds, whole grains and wheat germproviding additional sources. “Vitamin E” includes eight differentchemical forms: four tocopherols and four tocotrienols. The mostbiologically active form of vitamin E is alpha-tocopherol. Vitamin E isimportant in dogs. Phospholipids are a significant structural componentof photoreceptors and normal shedding and phagocytosis by retinalpigment epithelium produces a peroxidized lipoprotein or lipofusin fromthe lysosomes in the cell. A deficiency in vitamin E may result inpathologic changes in the muscle, central nerve system, reproductivetract and retina. Occular lesions such as cataracts, decreased vision toblindness and retinal degeneration occur with prolonged vitamin Edeficiency in dogs. Vitamin E supplement retards the intracellularaccumulation of oxidized lipoprotein or lipofusin pigment.

The composition of the present invention may comprise at least about0.01% of Vitamin E, by weight of the composition, from about 0.01% toabout 10% of Vitamin E, by weight of the composition, from about 0.2% toabout 5% of Vitamin E, by weight of the composition.

Vitamin C (as calcium ascorbate) is a water-soluble, found in aqueouscellular compartments and is a line of defense against direct freeradical exposure (e.g., radiation, sunlight). Vitamin C maintainsoxidative balance by effectively scavenging free radicals produced inthe aqueous cellular cytoplasm and by recycling (protecting) vitamin Ein cellular membranes. The preferred form of Vitamin C is as calciumascorbate. The chemical core of vitamin C is composed of a five-memberedlactone ring containing a bifunctionalene-diol group and an adjacentcarbonyl group. Ascorbate is highly soluble in water. The unusualchemical structure, thermodynamic redox potential and rapid reactionkinetics observed for ascorbate support its unique role as the terminalsmall molecule antioxidant in biological systems. Ascorbic acid (ASC)exists in three different redox states in biological systems: ASC,semidehydroascorbate (SDA), and dehydroascorbate (DHA). DHA is formed asthe result of two consecutive and reversible, one-electron oxidationprocesses. Because the unpaired electron is in a highly delocalized.pi.-system, the ascorbate radical is relatively unreactive. Thus, thethermodynamics and kinetics of ascorbate chemistry make ASC a superiorbiological donor antioxidant. SDA and DHA are recycled via reductionback to ascorbate by endogenous enzyme systems. It is believed thatascorbate enhances the antioxidant action of vitamin E by reducingreduction of the tocopheroxyl radical. The reactions between thetocopheroxyl radical and ascorbate provide a mechanism for exportingoxidative free radicals away from the cellular membranes. In essence,tocopherols protect membranes by stopping propagation reactions of lipidperoxy radicals and ascorbate acts by protecting the membrane againstpossible damage from the tocopheroxyl radical. Thus, ascorbate helps tomaintain oxidative balance by scavenging free radicals and recycling theuseful forms of other antioxidants, such as vitamin E.

The composition of the present invention may comprise at least about0.01% of Vitamin C, by weight of the composition, from about 0.01% toabout 10% of Vitamin C, by weight of the composition, from about 0.2% toabout 5% of Vitamin C, by weight of the composition.

Vitamin A and carotene can be obtained from either animal or vegetablesources. The animal form is divided between retinol and dehydroretinolwhereas the vegetable carotene can be split into four very potentgroups—alpha-carotene, beta-carotene, gamma-carotene andcrypto-carotene. Vitamin A is required for night vision. It assists theimmune system, and because of its antioxidant properties is great toprotect against pollution and other diseases.

Total Moisture Content Method

The method involves the analysis of the total moisture content in thecomposition. The analysis is based on the procedure outlined in AOACmethod 930.15 and AACC method 44-19.

A composition sample is prepared by taking one unit volume, for example,375 gram of the composition, and homogenizing in a food processor to auniform consistency like a paste. A composition larger than 375 gramwould be subdivided to create equal and representative fractions of thewhole such that a 375 gram sample is obtained.

The paste of the composition is individually sampled in triplicate at avolume less than or equal to 100 ml and placed individually sealed in a100 ml Nasco Whirl-Pak® (Fort Atkinson, Wis. 53538-0901). During theprocess of sealing the Whirl-Pak®, excess air is evacuated manually fromthe container just prior to final closure thereby minimizing thecontainer headspace. The Whirl-Pak® is closed per manufacturer'sinstructions—tightly folding the bag over three (3) times and bendingthe tabs over 180 degrees.

All samples are refrigerated at 6° C. for less than 48 h prior tomoisture analysis.

For total moisture analysis, the tare weight of each moisture tin andlid are recorded to 0.0001 g. Moisture tins and lids are handled usingdry and clean forceps. Moisture tins and lids are held dry overdesiccant in a sealed desiccator. A Whirl-Pak® containing a sample isunfolded and a 2.0000+/−0.2000 gram sample is weighed into the uncoveredmoisture tin. The weight of the sample in the moisture tin is recorded.The lid is placed atop the moisture tin in an open position to allowmoisture loss but contain all other material during air oven drying. Thelid and moisture tin loaded with sample are placed in an air ovenoperating at 135° C. for 6 h. Time is tracked using a count-down timer.

After drying, the tin is removed from the oven and the dried lid isplaced atop the tin using forceps. The covered moisture tin with driedsample is placed immediately in a desiccator to cool. The sealeddesiccator is filled below the stage with active desiccant. Once cool toroom temperature, the covered moisture tin with dried sample is weighedto 0.0001 g and weight recorded. The total moisture content of eachsample is calculated using the following formula:

Total Moisture Content (%)=100−(weight of tin, lid and sample afterdrying−empty tin and lid weight)×100/initial sample weight.
